Answer:

F. 120°

Step-by-step explanation:

Call the point of intersection of the altitudes X. Then the measure of n° is the sum of the opposite interior angles of triangle XNQ. Those angles are the right angle (90°) at Q and half the 60° vertex angle at N:

n° = 90° + (1/2)60° = 120° . . . . matches choice F

(sqrt(1/25 h^2))^2

we know that sqrt(ab) = sqrt(a) sqrt(b)

(sqrt(1/25) sqrt(h^2))^2

Which triangles are similar?

likoan [24]

Answer:

option B) ΔABE ∼ ΔADC

Step-by-step explanation:

The picture of the question in the attached figure

we know that

If two triangles are similar, then its corresponding sides are proportional and its corresponding angles are congruent

In this problem

Triangles ABE and ADC are similar by AA Similarity Theorem

because

m∠ ABE≅m∠ADC

m∠ BAE≅m∠DAC

The corresponding sides are

AB and AD

BE and DC

AE and AC

$\frac{AB}{AD}=\frac{BE}{DC}=\frac{AE}{AC}$
